django-deployer

django-deployer is a deployment tool for Django that currently deploys any Django app to the following PaaS providers: Dotcloud, Stackato, OpenShift and Google App Engine. The goal of django-deployer is to minimize the effort to deploy a Django app to any of the popular PaaS providers. It asks a series of questions about your Django project, and then generates a generic deploy.yml file that captures all of your project's requirements. django-deployer then uses this deploy.yml file to translate these requirements into specific configurations for each PaaS.

See the roadmap below for adding support for more providers: Heroku, OpenShift, Elastic Beanstalk and Gondor.

Getting Started

To install django-deployer, use pip to fetch the package from PyPi:

$ pip install django-deployer

Now from your project's root directory run the deployer-init command once, and then run fab setup.

In this example (using paasbakeoff), we are going to tell django-deployer to prepare our project to deploy to Google App Engine.

$ deployer-init
$ fab -f fabfile_deployer.py setup

    We need to ask a few questions before we can deploy your Django app
* What is your Django settings module? [settings]
* Where is your manage.py file? [./manage.py]
* Where is your requirements.txt file? [requirements.txt]
* What version of Python does your app need? [Python2.7]
* What is your STATIC_URL? [/static/]
* What is your MEDIA_URL? [/media/]
* Which provider would you like to deploy to (dotcloud, appengine, stackato, openshift)?
* What's your Google App Engine application ID (see https://appengine.google.com/)?
* What's the full instance ID of your Cloud SQL instance (should be in format "projectid:instanceid" found at https://code.google.com/apis/console/)?  * What's your database name?
* Where is your Google App Engine SDK location? [/usr/local/google_appengine]
* What do you want to set as the admin password?
    Creating a deploy.yml with your app's deploy info...
    Created /Users/nateaune/Dropbox/code/paasbakeoff/deploy.yml

    Just a few more steps before you're ready to deploy your app!

    1. Run this command to create the virtualenv with all the packages and deploy:

            $ fab -f fabfile_deployer.py deploy

    2. Create and sync the db on the Cloud SQL:

            $ sh manage.sh cloudcreatedb
            $ sh manage.sh cloudsyncdb

    3. Everything is set up now, you can run other commands that will execute on your remotely deployed app, such as:

            $ sh manage.sh dbshell

    Done.

Now inspect your project directory and you will see that a file deploy.yml and various config files were created.

Note: if you're going to try different PaaS providers, it's recommended that you make a separate git branch for each one, because when you re-run fab setup it could inadvertently overwrite the config files from the first run.

Upgrading

You will notice that when we ran pip install django-deployer it created a script deployer-init. When you ran this script, it created a fabfile.py in your current directory that imports the tasks module from the django-deployer project.

from django_deployer.tasks import *

This means that you can update the django-deployer package and don't need to regenerate the fabfile.

$ pip install -U django-deployer

Contribute

If you want to develop django-deployer, you can clone it and install it into your project's virtualenv:

$ source bin/activate
(venv)$ git clone git://github.com/natea/django-deployer.git
(venv)$ cd django-deployer
(venv)$ python setup.py develop

Or you can also install an editable source version of it using pip:

$ source bin/activate
(venv)$ pip install -e git+git://github.com/natea/django-deployer.git#django-deployer

Which will clone the git repo into the src directory of your project's virtualenv.

Roadmap

  • Add support for Heroku, OpenShift, Amazon Elastic Beanstalk and Gondor
  • Perform some intelligent code analysis to better guess the settings (see the djangolint project - https://github.com/yumike/djangolint)
  • Write tests!
  • Caching (Redis, Memcache)
  • Celery
  • Email
  • SSL
